I mean...it HAS been awhile since an Ally character really fell from grace. Sure Tyrande and Mal-TyrandeINEEDYOU-furion have been off having a huff about the ol' Tree, but we've made mega enemies out of how many Horde characters now? We have yet to see that with the Alliance. If we make Anduin the Lich King it would be an interesting plot piece BUT effectively would cause political upheaval for humanity in Stormwind as the Wrynn line would no longer be the leading Monarch. The Greymane line could take over but I feel it far more likely Anduin takes Tess or Taelia down to Bonerock Mountain (if you know what I mean) to make the next heir. Given that in Shadows Rising its alluded to that Flynn and Shaw become Brokeback bros, it opens the door for Taelia to pursue other love interests. Although she's pissed at Andy for holding back her father was alive it was like a state secret. Anyways. An ally leader becoming the next Lich King would be interesting, but I don't see it happening. Far more likely that when we get back from SL we have to fight the scourge since they have no leader. There must ALWAYS be a Lich King...and right now we don't has one. Unfortch.
